Erdős Problem #1016 — Let h(n)h(n) be minimal such that there is a graph on nn vertices with n+h(n)n+h(n) edges which contains a cycle on kk vertices, for all 3≤k≤n3\leq k\leq n.

Let h(n)h(n) be minimal such that there is a graph on nn vertices with n+h(n)n+h(n) edges which contains a cycle on kk vertices, for all 3≤k≤n3\leq k\leq n. Estimate h(n)h(n). In particular, is it true that h(n)≥log⁡2n+log⁡∗n−O(1),h(n) \geq \log_2n+\log_*n-O(1), where log⁡∗n\log_*n is the iterated logarithmic function?
